摘要： A switching valve assembly for an endoscope (10) has a cylinder (50) and a piston unit (51) , which includes a valve head (51b) , a flow channel (71, 72), an end rod (51a) and a button device (43, 47). The piston unit is settable in an initial position, a down position and a halfway position to change over flow lines (28, 46). A biasing unit (52) of a two-stage type is secured to the cylinder on an upper side of the cylinder passage, biases the piston unit, and stops the piston unit in the halfway position when the button device is pushed in a downward direction from the initial position. A first regulating device (67, 102) prevents the piston unit from rotating relative to the biasing unit. A second regulating device (64, 94) prevents the biasing unit from rotating relative to the cylinder, so as to ensure alignment of a channel opening of the flow channel with one of the flow openings upon sliding the piston unit.

摘要： The present invention provides an ultrasonic endoscope in which wiring can be reliably fixed to a wire housing space of an ultrasonic-oscillator housing part, and a method of manufacturing the ultrasonic endoscope. According to the present invention, a wire housing space 112 is encapsulated from the outside by sealing a gap formed between an ultrasonic oscillator 80 and an ultrasonic-oscillator housing part 96 with sealing members 98 and 110. With this configuration, the wire housing space 112 can be sufficiently filled with filling agent for fixing wires 94 in the wire housing space 112. This achieves an ultrasonic endoscope 10 in which the wires 94 can be reliably fixed to the wire housing space 112 of the ultrasonic-oscillator housing part 96.

摘要： There are provided an ultrasound diagnostic apparatus and an operation method of an ultrasound diagnostic apparatus capable of performing polarization processing during the execution period of ultrasound diagnosis without affecting the image quality of an ultrasound image. In the ultrasound diagnostic apparatus and the operation method of the ultrasound diagnostic apparatus of the invention, a trigger generation circuit generates a trigger for starting polarization processing. After a trigger is given, during the execution period of ultrasound diagnosis, in a non-diagnosis period which is a period other than a period for acquiring an image of each frame and during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, within each frame time in which an image of each frame of an ultrasound image is acquired, a control circuit performs polarization processing on a plurality of ultrasound transducers.

摘要： In an ultrasound diagnostic apparatus and an operation method of the ultrasound diagnostic apparatus of the invention, a control circuit performs polarization processing on a plurality of ultrasound transducers in a non-diagnosis period, during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, in a case where the cumulative driving time of the plurality of ultrasound transducers for performing the ultrasound diagnosis becomes equal to or longer than a specified time. A transmission circuit generates a first transmission signal having a driving voltage for performing ultrasound diagnosis using a pulse generation circuit in the case of performing the ultrasound diagnosis, and generates a second transmission signal having a polarization voltage for performing polarization processing using the same pulse generation circuit as in the case of generating the first transmission signal in the case of performing the polarization processing.
